Remove bay windows and prepare apertures
Overview
This standard applies to the removal of bay windows and preparing apertures during the refurbishment of a property. This standard would not be appropriate for a new building or new installation. You will need to remove existing bay windows, using appropriate supports, and restructure apertures or create new openings as required. You will need to check apertures against specifications, and remove all debris. Finally, you will need to provide new surface finishes ready for installation
This standard is for you if you work in the Fenestration Industry and are involved in on site removal of bay windows and preparation of apertures for installation work
Performance criteria
You must be able to:
check for structural problems, dangerous materials and infestations that could affect the removal and installation
prepare internal and external parts of dwellings for the removal of bay windws to keep damage/disruption to a minimum and protect others
identify fixtures and fittings that will prevent or restrict installations following stanadrd operating procedures
remove and store fixtures and fittings to allow effective refitting
identify and position temporary structural supports at support bearing points following safe working practices
remove components, materials and outer frames from apertures following safe working practices in ways that cause minumum damage to the structures and surounding areas
inspect, fit and replace any existing damp-proof barrier required to meet specifications
cut materials to size and shape required to meet specifications, minimising waste and following safe working practices
assemble materials following manufacturers' instructions to meet specifications
check materials fit level and plumb to prepared apertures using appropriate equipment and methods
identify and create suitable fixing points to meet specifications
- check new or restructured apertures meet specifications
